Donald Trump revealed that he is sleeping four to five hours a night in his new life as the US top dog. "I'm working long hours, long hours, right up til 12 o'clock, 1 in the morning." What time does he get up? "Five. I eat, I read the papers, I see what's going on on TV." Five hours actually represents a very healthy night's sleep for The Don. While on the campaign trail, Trump put the figure at just three to four hours – a habit that he claims helped him to succeed in the business world. “How does somebody that’s sleeping 12 and 14 hours a day compete with someone that’s sleeping three or four?” Trump's miserly approach to getting some shut-eye puts him firmly in the category of what the Wall Street Journal once termed the "sleepless elite": the one per cent of the population who need very little sleep to get by. According to research, it's a gene thing: short sleepers tend to run in the family. They're also more likely to be optimistic and upbeat than us seven-hour-a-night mortals and find they don't need caffeine to feel energetic.
